Abstract
Embodiments of the present disclosure provide a method, apparatus, and computer-readable medium for authentication. According to an embodiment of the present disclosure, only the first terminal device in the group of terminal devices that requests to connect to the network needs to complete the entire authentication. After the first terminal device has successfully accessed the network, the remaining terminal devices in the same group may ignore the authentication. In this way, the authentication time is reduced and, for a large number of terminal devices, the computational effort related to authentication is reduced.

Embodiments of the present disclosure may be applied to various communication systems. Given the rapid development of communications, there will of course also be future types of communication techniques and systems that may embody the present disclosure. The scope of the present disclosure should not be limited to the above-described systems.
The term "network device" includes, but is not limited to, a Base Station (BS), a gateway, a management entity, and other suitable devices in a communication system. The term "base station" or "BS" denotes a node B (NodeB or NB), evolved NodeB (eNodeB or eNB), remote Radio Unit (RRU), radio Header (RH), remote Radio Head (RRH), relay, low power node (e.g., femto, pico, etc.).

As described above, in a communication system, there is often an authentication procedure between a terminal device and an entity in a network. Communication systems such as 3G systems or 4G systems typically use message authentication codes. It usually takes some time to complete the authentication process. Some signaling is also transmitted between the terminal device and the entity during authentication.
However, in 5G systems, especially in the case of the internet of things (IoT), there are a large number of connections between the terminal devices and the network, since the terminal devices are ubiquitous. Conventional authentication mechanisms can take a long time to authenticate a terminal device in the IoT and introduce a signaling storm.
To address at least in part the above and other potential problems, embodiments of the present disclosure provide a solution for authenticating a terminal device. Generally, according to embodiments of the present disclosure, for a group of terminal devices, only the first terminal device accessing the network needs to complete the entire authentication process. The remaining terminal devices in the same group may ignore the authentication procedure if they request access to the network.
Some example embodiments of the present disclosure are now described below with reference to the drawings. Those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the disclosure extends beyond these limited embodiments.
Fig. 1 shows a schematic diagram of a communication system in which embodiments of the present disclosure may be implemented. Communication system 100, which is part of a communication network, includes network device 120 and terminal devices 110-1, 110-2, \ 8230 \ 8230;, 110-N (collectively, "terminal devices" 110). It should be understood that the number of network devices and terminal devices shown in fig. 1 is given for illustrative purposes and does not suggest any limitation. Communication system 100 may include any suitable number of network devices and terminal devices. It should be noted that communication system 100 may also include other elements that are omitted for clarity. Network device 120 may communicate with terminal device 110.
Terminal devices 110-1, 110-2, \8230 \ 110-N belong to the same terminal device group 110. For example only, in an IoT scenario, terminal devices with similar applications may be classified into the same group. For example, shared bicycles or vehicles may be classified into the same terminal device group.
Alternatively or additionally, in some embodiments, terminal devices may also be classified based on location. For example, terminal devices in the same industry product line may be classified into the same group. Alternatively or additionally, in some embodiments, terminal devices requiring the same quality of service (QoS) may be classified into the same group. It should be appreciated that the terminal devices may be classified into groups in any suitable way based on any suitable conditions. The present disclosure is not limited in this respect.
Communications in communication system 100 may be implemented in accordance with any suitable communication protocol, including but not limited to first-generation (1G) cellular communication protocols, second-generation (2G) cellular communication protocols, third-generation (3G) cellular communication protocols, fourth-generation (4G) cellular communication protocols, fifth-generation (5G) cellular communication protocols, and/or the like, wireless local area network communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, and/or any other protocol currently known or later developed. Further, the communication may utilize any suitable wireless communication technology, including but not limited to: code Division Multiple Access (CDMA), frequency Division Multiple Address (FDMA), time Division Multiple Address (TDMA), frequency Division Duplex (FDD), time Division Duplex (TDD), multiple Input Multiple Output (MIMO), orthogonal Frequency Division Multiple Access (OFDMA), and/or any other currently known or later developed technique.
Fig. 2 is a diagram 200 illustrating interaction between a terminal device and a network device according to the conventional art. As described above, conventional authentication mechanisms use message authentication codes to authenticate a terminal device, where a root key is shared between the terminal device and a network device. Fig. 2 shows an example authentication procedure between the terminal device 210, the network device 220 and the further network device 230.
Upon receiving the authentication data request, the further network device 230 may generate a Ciphering Key (CK) and an Integrity Key (IK) based on the shared root Key. The further network device 230 may generate 2030 an authentication vector. The further network device 230 may transmit 2040 an authentication data response to the network device 220. The authentication data response may include the generated authentication vector. The authentication data response may include other information generated by the further network device 230. The authentication data response may also include a random number (RAND), for example. Additionally, the authentication data response may include an authentication token (AUTN). The authentication data response may also include an expected response (XRES). Network device 220 may save 2050 vectors.
The network device 220 may transmit 2060 a user authentication request to the terminal device 210. The user authentication request may contain a relevant parameter, a message authentication code value. The relevant parameters may include RAND and/or AUTH. The terminal device 210 may calculate the expected authentication message code and XRES to authenticate 2070 network. The terminal device 210 may generate a 2080 Response (RES) and transmit a 2090 user authentication response to the network device 220. The user authentication response may include the generated RES. Network device 220 may check that 2100RES is equal to XRES.
The network device 220 may transmit 2110 a response to the attach request based on the result of the check. For example, if RES is equal to XRES, network device 220 may successfully authenticate terminal device 210 and transmit a response to indicate that the attach request was accepted.
It should be appreciated that interaction according to conventional authentication, as shown in fig. 2, typically takes a relatively long period of time to complete authentication. Since each terminal device needs to complete the entire authentication as long as it accesses the network, the authentication may take a long time if there are many terminal devices. Furthermore, there may be a large amount of signaling due to the number of terminal devices. Therefore, new authentication solutions are needed.
Unlike the authentication process described above, the present disclosure provides an IBC-based method for authenticating a terminal device. Identity-based cryptography (IBC) is a public-key cryptography that employs a bilinear mapping technique that does not require rules to pre-compute key pairs or certificates to obtain their public keys. Instead, the public key may be any identifier, such as an email address, while the private key is derived by the trusted private key generator at any time when requested by the designated principal.
Fig. 3 is a schematic diagram 300 illustrating interactions between a terminal device and a network device. As shown in fig. 1 and 3, terminal device 110-1 belongs to terminal device group 110. The group identification of each group is shared between the respective group and the network 105.
Terminal device 110-1 transmits 3010 a connection request to network device 120 in network 105. The connection request includes an identification of terminal device 110-1. For example, the identity of terminal device 110-1 may include, but is not limited to, an International Mobile Subscriber Identity (IMSI) of terminal device 110-1, a packet temporary Mobile subscriber identity (P-TMSI) of terminal device 110-1, a globally unique temporary UE identity (GUTI) of terminal device 110-1. It should be appreciated that the connection request may include any one or any combination of the above identifications. Alternatively or additionally, the connection request may include a signature (hereinafter referred to as "first signature") of the terminal device 110-1. In some embodiments, the first signature may be verified by network device 120 during authentication, as will be described below. In some embodiments, the connection request may be an access request to the network 105. In other embodiments, the connection request may be a service request. It should be appreciated that the connection request may be any kind of suitable request.
Upon receiving the connection request, the network device 120 obtains 3020 a group identity for the group of terminal devices based on the identity of the terminal device. In some embodiments, network device 120 may map the identity of terminal device 110-1 to a group identity based on a predefined mapping. As described above, the group identification of each group is shared between the respective group and the network 105. In some embodiments, if a terminal device enters group 110, the identity of the terminal device is stored in association with the group identity, and such information is updated to network 105.
In some embodiments, the predefined mapping may be generated after the terminal devices are classified into groups. The predefined mapping may be stored in the network. Each terminal device group has a respective predefined mapping. For example, all predefined mappings for each group may be stored in a further communication device 130 having a large amount of memory space, and/or may be stored in a remote memory device accessible by the further communication device 130. In an example embodiment, some set of predefined mappings may also be stored in network device 120.
In an example embodiment, the predefined mappings may be stored in table form. Alternatively, the predefined mappings may be stored in the form of a tree. It should be appreciated that the predefined mapping may be stored in any suitable manner.
If the group identification is not pre-stored in network device 120, network device 120 may not find the group identification corresponding to the identification of terminal device 110-1. In this case, the network device 120 may transmit 3030 an authentication request to the further network device 130 in the network 105 in order to obtain the group identification and the group status of the group. The authentication request may include an identification of the terminal device 120. For example, the authentication request may include the IMSI of terminal device 110-1. Alternatively or additionally, the authentication request may include a Service Network (SN) identification. In other embodiments, the authentication request may include a network type. It should be understood that the present disclosure is not limited in this respect.
In an example embodiment, the further network device 130 may be a HSS. Alternatively or additionally, the further network device 130 may be a home gateway or an entity in a Home Environment (HE). As mentioned above, the further network device 130 may store a mapping between the identity of the terminal device and the identity of the group. For example, another network 130 may store a mapping relationship between the identities of end devices 110-1, 110-2, \8230;, 110-N and the group identity of group 110. In other embodiments, the additional network devices 130 may be capable of accessing remote storage that stores the mapping.
In some embodiments, upon receiving the authentication request from network device 120, further network device 130 may find 3040 a group identification based on the identification of terminal device 110-1. As mentioned above, the further network device 130 stores locally or remotely all mappings between identifications of terminal devices and identifications of groups. Further network device 130 may look up the group identification of group 110 in the mapping corresponding to the identification of terminal device 110-1. The group identification of group 110 may be denoted "Vtl _ Grp _ ID".
The further network device 130 may also store the group status for each group. The group status relates to historical access of the group of terminal devices to the network 105. The group identification has one or more attributes for indicating the group status. For example, the group status may be a boolean value. In other embodiments, the group status may be one bit in the group identification. For example, if the group status is "0" (false), it indicates that no terminal device in the group has previously accessed the network. If the group status is "1" (true), this indicates that at least one terminal device in the group has previously accessed the network.
The additional network device 130 may transmit 3050 the group identification and group status to the network device 120. Network device 120 may store the group identification and group status from additional network devices 130. In this way, the additional network device 130 does not need to generate an authentication vector and saves space for storing the authentication vector at the network device 120.
In some embodiments, network device 120 may obtain 3060 the first signature from the received connection request and then verify 3070 the first signature based on a public key derived from the group identification. In an example embodiment, since IBC is a kind of public key cryptography, the first signature may be decrypted using a public key (i.e., a public key) obtained from the group identification. If network device 120 fails to verify the first signature, network device 120 may deny the connection request.
If the group status indicates that at least one terminal device in group 110 previously accessed network 105, it means that terminal device 110-1 is not the first terminal device in group 110 to request access to network 105. In this case, network device 120 transmits 3100 a response to the connection request. The response may indicate that the connection request is approved and terminal device 110-1 may ignore the subsequent authentication and connect directly to the network. In this manner, both network device 120 and terminal device 110-1 may reduce authentication time, thereby improving authentication efficiency.
In some embodiments, the response may include an "auth _ pass _ ind" indicator. In this way, if the network device 120 stores the group identity in advance, the network device does not need to communicate with the further network device 130 for authentication, which reduces the number of signaling and saves time compared to conventional techniques. Further, terminal device 110-1 does not need to authenticate network 105, which reduces the computational burden on terminal device 110-1.
In some embodiments, if the group status indicates that no terminal device in group 110 previously accessed network 105, it may be determined that the connection request is associated with initial access to network 105 by group 110 and that terminal device 110-1 is the first terminal device in group 110 to request access to network 105. In some embodiments, after verifying 3070 the first signature, network device 120 may generate 3090 its signature (hereinafter referred to as "second signature") to be verified by terminal device 110-1. The network device 120 transmits 3100 a response to the connection request, the response including the second signature and the verification of the first signature.
In some embodiments, upon receiving the response to the connection request that includes the second signature, terminal device 110-1 may verify 3110 the second signature based on the public identification of network device 120 to authenticate network 105. If terminal device 110-1 successfully verifies the second signature and authenticates the network, terminal device 110-1 may transmit 3120 authentication information to network device 120. Upon receiving the authentication, network device 120 may set a group status of group 110 to indicate that at least one terminal device in group 110 has access to network 105.
In this way, for a group of terminal devices, only the first terminal device of the access network needs to complete the entire authentication process, and the remaining terminal devices in the same group can ignore the authentication, thereby saving a lot of computing effort and authentication time. Furthermore, there is no dedicated authentication message between the terminal device and the network device.
Fig. 4 shows a flow diagram of a method 400 according to an example of the present disclosure. Method 400 may be implemented at network device 120.
